1. Updates from Annual meeting

• Extensive interest from the OHDSI community with reference to the text processing aspect. During the meeting, suggestions for improvements in the current projects were received.

1. IRB for use of clinical text

• IRB language pertaining to textual part of the record is being compiled from multiple sources.
• Anu will collect and generate a generic document for use as an example.
• Once approval of the document is obtained from the contributors, the document will be posted online for use by the OHDSI community.

1. Clinical text data storage and representation schema

• Minimum set of modifiers for all clinical entities that support use of rule to derive clinical concepts will be generated by Alex (Columbia).
• To classify the notes for the representation schema, metadata about the notes with note-type defined in detail and mapped to LOINC codes will be generated.
